PAPER-GUIDE FOR TYPE-WRITERS.

'State of Illinois, have invented certain new" and useful Improvementsin Paper-Guides for Typejtvrlters. of which the. following 1s aspecitication.

This invention relates to adjustable paper guides for holding the paperfirmly against the platen during the typewriting operation; and theobject ot' tbe invention is to so constructI and mountthe guides thatthey may be individually adjusted to an)I suitable poi sition withrespect toA thel platen, and so that ample space will be a'orded behindthe rod on which the guides are mounted for erasures` and for theeasymanipulation of the paper.

Further objects will appear from a detailed description of theinvention, which consists in the features of construction andcombination of parts hereinafter described and claimed.

In the drawings- Figure 1 is a front elevation of a typewriter carriageand platen, showing the paper guides in their relation thereto; F ig. :2a cross sectional view of the platen and carriage, showing one of theguides in elevation; Fig. 3 an enlarged sectional elevation of one ofthe guides; and Fig. 4 a sectional detail, taken on line, li--t of Fig.3.

Referring to Fig. 1, the paper guides are carried upon a rod 5 which isprovided -with a flat side 6, the ends of which rod are supported byforwardly projecting arms 7 formed on the end plates 8 of the carriageframe. The construction of the carriage and associated parts forms nopart of the resent invention and need not be described 1n detail. Thecarriage frame serves to mount a platen 9 located diagonally to the rearand below the rod 5, space being afforded behind the rod to permit theoperator to manipulate an eraser when it is desired to make erasures onthe paper. Each of the paper guides comprises a flat plate l() provided,at its ends, with inturned ears 11 which are bored to receive the rod 5,and the plate l0 norm-illy extends diagonally toward the center or Lieplaten and is provided, at. its lower end, with a curved `linger 12adapted to press against the surface of the platen, the lower edge 13 ofwhich is si'iglitly bent away from the platen to facilitate the initialSpecification of Letters Patent. latenfpd F91), 22, 1910.

t )ositioning of the paper which is fed down l )elow thc platen and overa curved guide plate 14. the forward edge of which is closely l adjacentto and behind the curved lower edge of the nger 12, so that the papel'will slip easily from the guide plate behind the linger. Oneach side ofthe.ti ger 12, at its t point of connection with the plate 10, is arearwardly extending tongue 15 which overlies the platen'and is curvedin register' with the curvature of the linger. which line of curvature,as shown in F ig. 2, is of a slightlyr greater radius than that. of thesurface of the platen, so that the paper will begnessed against theplaten at a single point which is at or in 'proximity to the printingline.

i l i I Il@ plate 10, at its outer edge, is bent at right angles toafford an upper plate 1G which overlaps the upper edges of the ears 11and is given a curvature commensurate with the curvature of said ears.The upper plate exof the ears and terminates in a handle 1T whichextends diagonally upward from the rod 5 and permits manipulation of theguide as a whole. The plate 10 is provided, on its inner face, with abow spring 1S which presses against the rod 5 and is adapted to normallyabutagainst thc tintface (3 of the rod in such a manner as to hold thefingers of the guides under tension againstthe. surface of the paper.

In use, the guides can be adjusted to any placement by the pressure ofthe bow springs, which, however, are not of Sutlicient tension toprevent easy manual manipulation of the guides. When the paper is beinginitially inserted, the 'guides can be thrown out of contact with theplaten by pressing on the handles 17, which pressure serves to lift thelingers 12 away from the platen, so that the paper can be easilyinserted. Thereafter the guides can be snapped back into engagingposition and held during the operation ofthe machine.

The construction of the guides is one which ermits them to be easilstamped or blocked) out of a plate of meta each of the guides beingformed of a single piece of metal, with the exce tion of 'the s rings,so that the cost of tlie guides will extremely small and the expense oftheir assembling reduced to a minimum. The artends around substantiallythe upper halt` desired position along the rod and will be held againstaccidental longitudinal dis-V 2 asdieo rangement, furthermore, is onewhich is -extreniely effective in the addressing of envelops o1' otherrelatively thick paper, since the guides can be adjusted to leave onlythe necessary space between there for receiving the intended typewritinthereby holding the surface of the envelop firmly against the platen,which isfoften ditlieult in the addressing of envelops on typewriters ofthe usual character.

vWhat l regard as new and desire to secure bj: Letters Patent is:

l. ln a device of the class` described, in combination with a platen, arod mounted adiacent to the pla ten the rod provided with a flattenedface, a guide comprising upper and lower plates bent at an angle to oneanother. one of the plates beingrprovided, at. its edges, with inwardlytamed ears having holes through which the rod extends, the upper plate.terminating in an angularlj.' disposed handle, the lower plateterminating in a (leperl ig curved iin er, and a bow .s ring connectedwith one o the plates and adapted to bear against the rod, for holdingthe guide in adjusted position when said bow spring @intacts theflattened face of said rod, suiislantiaily as described.

:2. ln a device of the class described, in combination with a plaien, arod mounted adjacent to the pieten the rod provided with a flattenedface, a guide comprising upper and lower nietes bent at an angle to oneanother, one o the plates being provided, at its edges, with inwardlyturned ears having holes through which the rod exlends, the upper plateterminating in an angolari); disposed handle, the lower plateterminating in a depending curved finger, the lower plaie being furtherprovided on each side o the nger with upwardly extending tongues, and abow spring interposed between one of the plates and the rod, 'forholdin# the guide in adjusted osition when said bow spring contacts theattened face of said rod, substantially as described. 3. ln a device ofthe class described, in combination with a platen, a rod mountedadjacent to the platen the rod provided with a flattened face, a guidecomprising upper and lower plates bent at an angle to one another, oneof the plates being provided, at its edges, with inwardly turned earshaving holes througi which the rod extends, the upper plate havingconnected therewith a handle, the lower plate terminating in -adepending curved finger, and a bow spring connected with one of thepistes and adapted to bear against the rod for holding the guide inadjusted position when said bow spring contacts the flattened face ofsaid rod, substantially as described. l
